Gravel

Gravel /ˈɡrævəl/ is composed of unconsolidated rock fragments that have a general particle size range and include size classes from granule- to boulder-sized fragments. Gravel is categorized by the Udden-Wentworth scale into granular gravel (2 to 4 mm or 0.079 to 0.157 in) and pebble gravel (4 to 64 mm or 0.2 to 2.5 in). One cubic yard of gravel typically weighs about 3000 pounds (or a cubic metre is about 1,800 kilograms).

Gravel is an important commercial product, with a number of applications. Many roadways are surfaced with gravel, especially in rural areas where there is little traffic. Globally, far more roads are surfaced with gravel than with concrete or tarmac; Russia alone has over 400,000 km (250,000 mi) of gravel roads. Both sand and small gravel are also important for the manufacture of concrete.

Geological formation

Large gravel deposits are a common geological feature, being formed as a result of the weathering and erosion of rocks. The action of rivers and waves tends to pile up gravel in large accumulations. This can sometimes result in gravel becoming compacted and concreted into the sedimentary rock called conglomerate. Where natural gravel deposits are insufficient for human purposes, gravel is often produced by quarrying and crushing hard-wearing rocks, such as sandstone, limestone, or basalt. Quarries where gravel is extracted are known as gravel pits. Southern England possesses particularly large concentrations of them due to the widespread deposition of gravel in the region during the Ice Ages.

Mike Gravel presidential campaign, 2008

Mike Gravel, a former United States Senator from Alaska, on April 17, 2006, declared his candidacy for the Democratic nomination for President of the United States in the 2008 election, in a speech to the National Press Club.

His campaign gained an Internet following and national attention due to outspoken debate appearances during 2007, but consistently showed little support in national polls. In the 2008 Democratic caucuses and primaries, he did not win any delegates. Out of the eight candidates for the Democratic nomination for president, he received the fewest votes - less than one percent.

In March 2008, Gravel announced that he had joined the Libertarian Party and would seek its presidential nomination, instead of further pursuing the Democratic nomination. In May 2008, Gravel finished fourth at the 2008 Libertarian National Convention and ended both his presidential quest and his political career.

Announcement

On April 17, 2006, Gravel became the first candidate for the Democratic nomination for President of the United States in the 2008 election, announcing his run in a speech to the National Press Club in Washington, D.C. Short on campaign cash, he took public transportation to get to his announcement.

The version of "Torture Day" on this EP features the vocals of Cindy Dall.

Track listing

Untitled (Marc and the Mambas album)

Untitled is the first studio album by the British singer/songwriter Marc Almond's band Marc and the Mambas. It was released by Some Bizzare in September 1982.

Background

Untitled was Almond's first album away from Soft Cell and was made concurrently with the latter's The Art of Falling Apart album. Almond collaborated with a number of artists for this album, including Matt Johnson of The The and Anni Hogan. The album was produced by the band, with assistance from Stephen Short (credited as Steeve Short) and Flood.

Jeremy Reed writes in his biography of Almond, The Last Star, that Untitled was "cheap and starkly recorded". He states that Almond received "little support from Phonogram for the Mambas project, the corporate viewing it as non-commercial and a disquieting pointer to the inevitable split that would occur within Soft Cell". An article in Mojo noted that "from the beginning, Almond and Ball had nurtured sideline projects, though only the former's - the 1982 double 12 inch set Untitled - attracted much attention, most of it disapproving." The article mentions that Almond "who preferred to nail a song in one or two takes" stated that it was all "about feel and spontaneity, otherwise it gets too contrived" when accused of singing flat.<ref name"mojo">Paytress, Mark.
